Marvell/Drivers: MvSpiFlash: Fix usage of erase size parameter

Although, hitherto support allowed for using configurable EraseSize,
the erase command was fixed to CMD_ERASE_64K. Also it was
assumed that EraseSize equals SectorSize, which is not true
for some flash devices. Fix both issues by adding new PCD
(gMarvellTokenSpaceGuid.PcdSpiFlashPageSize) and using
this parameter properly in MvSpiFlashUpdate routine instead
of the EraseSize. Also erase command is adjusted to the settings.
Update PortingGuide accordingly.
